If both healthy parents carry the same altered recessive. gene, then each child they have has a 25% (1 in 4) risk of. inheriting the altered gene from both parents and therefore. being affected. For each child, regardless of their sex, the. risk is the same = 25%. Children of couples who are both carriers of the same. altered recessive gene have a 50% (1 in 2) chance of. inheriting one copy of the altered gene from one of their. parents. If this happens, they are healthy carriers. themselves.
Print. To have an autosomal recessive disorder, you inherit two mutated genes, one from each parent. These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene (recessive gene) and one normal gene (dominant gene) for the condition.wo carriers have a 25 percent chance of having an unaffected child with two normal genes (left), a 50 percent chance of having an unaffected child who also is a carrier (middle), and a 25 percent chance of having an affected child with two recessive genes (right).
